HARROW. V

SPECIFICATION forming part of Letters Patent No. 367,665, dated August 2, 1887.

Application filed July 2.), 1886.

To aZZ whom, it may concern:

Be it known that we, HENRY RICKE, of East Dubuque, in the county of Jo Daviess and State of Illinois, and CHRISTOPHER J. BANNI- GAN, of Jamestown, in the county of Grant and State of \Visconsin, have invented certain new and useful Improvements in Harrows; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itpertains to make and use the same.

Our invention relates to barrows, one ofthe objects being to provide a novel means forsecuring the teeth to their beams.

A further object of the invention is to pro vide a ready means for adjusting the toothbeams to incline the teeth.

A further object is to provide a tooth of novel construction specially adapted for use with our securing devices.

A further object of the invention is to improve the devices for attaching the draft appliances.

Our invention consists in combining with the tooth-beams and the teeth clampingbars for securing the latter.

The invention further consists in the adj nsting devices to be described, in the novel form of the tooth shown, and in the various features of construction and combinations of parts, as fully set forth hereinafter.

In the drawings, Figure 1 is a perspective view illustrating a twosection harrow embodying our improvements. Fig. 2 shows a portion of one of the sections with the teeth inclined. Figs. 3 and 4 represent, respectively, a single and adoubleharrow-tooth constructed in accordance with our invention. Fig. 5 isa view in perspective of a part of one of the harrow-sections suflicient to clearly show the adjusting devices;v and Figs. 6, 7, and S illustrate parts in detail.

As both of the harrow sections shown are of the same construction, a description of one will suffice for both.

A represents the tooth-beams, preferably of wood, and B indicates the clampingbars, one for each beam A, and preferably made of metal considerably thinner than the tooth-beams. The drag-bars G are secured'below the beams A by hangers c, which are bent at their upper Serial No. 200.400. (No model.)

ends to form open loops 0 to embrace the bolts 0', passing through the beams A and the bars 13. The ends of the drag-bars are bent to form hooks c to receive the draft-chains, as shown.

The teeth D may be either single or double, as shown in Figs.3 and 4, and in either instance they are bent upon themselves to form loops (7, which embrace the bolts (1, passing through the clampingbars and beams A. The double teeth we design to use upon one beam only (say the second beam A from the front of the barrow) where large clods or lumps are to be broken up before contact with the smoothing single teeth, which will bein the rear; but of course we do not limit ourselves to any particular arrangement of the single or double teeth.

E represents an adj listing-bar consisting of two sections, 0 6, each being perforated at its inner end to receive a bolt, e.

F represents an adjusting-lever preferably bent as shown, and supported at its lower end in a socket,f, secured centrally between one of the clamping-bars Band the adjacent beam A. This lever passes through an eye, f, projecting from the adj usting-bar E, and is controlled in its movements by a spring-catch device consisting of a block, 0, and a slotted bent spring, 0. This catch is secured removably to the bar E by a bolt, 0, which passes through the catch and through one of the perforations of the adjustingbar E. The catch is steadied and further secured by a headed rod, P, whose head is perforated to receive bolts 1) to secure it to the catch,'while the free end of the rod rests in an eye, 1), projecting from the bar E. The free end of the spring 0 bears against the lever, and one side, 8, of the latter is beveled to permit its passing the spring when the lever is turned.

G represents a spanning-brace bent downwardly at each end to enter the eyes of the eyebolts y, projecting from the inner dragbars of each harronwsection opposite each other, as shown. This brace, in connection with the draft-coupling bar H, holds the two harrow-sections in proper relative positions, and the brace may be detached and fitted to the eyes g y when the draft is changed to the rear of the harrow. Upon the draft-coupling bar H we arrange a shifting plate, 71, having a ICC bar E at the point T.

downwardly-projecting lug, h, to engage the front edge of the bar H, and having also adepressed seat, h, to receive a coupling-hook, I. The plate h is secured adj ustably by a clamp, J, held by bolts j, and said plate may be adjusted upon the bar H, if desired, to incline slightly to the right or left before the clamp J is applied. The link or hook I, after attachment to the ring K of the draft-trees, may be slid backward to prevent accidental displacement ofv the ring.

By the construction above described we provide a ready and reliable means for securing the teeth, and the form of the latter is such as to facilitate their attachment or removal.

To incline the teeth of the two front or forward beams A, it is only necessary to remove the bolt 0 and adjust the front section, e, of the bar E rearwardly and then replace the bolt.

The two rear beams A A are adjusted to an inclined position by removing the spring-catch to another of the perforations of the bar E.

It will thus be seen that we may set the teeth of the forward beams at an inclination opposite to that of the teeth of the rear beams, while the central teeth remain vertical, and thus produce a thorough agitation of the soil, and combining in the harrow the functions of a pulverizer, agitator, and smoother.

To change the draft to the rear of the harrow, the lever F is turned (the beveled face 8 permitting it to pass the spring 0) and the spring-catch O is removed and secured to the The spanning-brace G- isalso changed, as above suggested, and the draft-bar H,with its attachmeuts,is secured to the rear ends of the drag-bars.

Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a harrow, the combination, with the drag'bars and tooth-beams, of clamping-bars secured to the tooth-beams, teeth bent upon themselves, and hangers secured to the dragbars, said clamping-bars adapted to clamp the bent portion of said teeth and also the bent portion of said hangers, substantially as de- .tooth-beams, of an adjusting-bar and an adjustable springcatch for holding the lever in its adjusted position, substantially as described.

5. The combination, with one of the toothbeams and its clamping-bar, of a socket sup-.

ported between the beam and clan'iping-bar, a lever pivotally seated in said socket, an adjustable bar, and'a removable spring-catch supported upon the adjusting-bar, substantially as described.

6. The combination, with a draft-bar, of a device for attaching the single or double-trees, said device consisting of a shifting plate, an adjustable hook, and a removable clampingplate, substantially as described.

In testimony whereof -we have signed this specification in the presence of two subscribing witnesses.
